Forming Operations

Forming operations we can perform in the development of precision deep drawn parts and metal stamping include:

Beading Rib-like projections mounted on either the binder or the draw ring surface that restrict and control metal flow into the die cavity and over the punch of a draw die. Simply put, draw beads act as speed bumps for material traveling into the die cavity.

BULGING / DIMPLING Localized indent forming, so as to permit the heat of a rivet or a bolt to fasten down flush with the surface of the metal.

KNURLING / EMBOSSING A process that produces relatively shallow indentations or raised designs with no significant change in metal thickness.

FLUTTING / RIBS Often used to impart rigidity to a part which otherwise might be too flexible and weak.

LETTERING / MARKING Process to add identification such as numbers, letters or graphics to a part.

SIDE STABBING / MULTISIDE PIERCING / HOLES A shaped portion of metal is cut from the drawn part using conventional, extruding, or piercing punches.

REVERSE DRAW / EXTRUDING Turning up or drawing out a flange around a smaller hole; also called “hole flanging.”

STEP DRAWING When 2 or more different diameters are needed on a part.

THREADING Threads are formed on a part using a roll and arbor.

Many other required metal stamping part features can also be performed in our transfer presses. Contact us today to discuss the requirements of your project.
